Check Microsoft Silverlight on your Mac OS

Microsoft Silverlight Version 3 can only be installed on Macs with an Intel processor. Please check whether your Mac has an Intel processor: In the “Finder”, choose “About This Mac” in the Apple menu. The installed processor is shown in “Processor”, e.g. “1.83 GHz Intel Core Duo”.

If you receive a message saying that Microsoft Silverlight must be installed, although you have already done so, please proceed as follows:

Step 1
Is the latest version of Microsoft Silverlight installed?

Step 2
Is Microsoft Silverlight activated in your Internet browser?

  • Launch Mozilla Firefox.
  • Click on “Extras” > “Add-Ons” > “Plug-Ins” > “Silverlight Plug-In”.
  • Activate the plug-in by clicking the “Activate” button.
  • Restart Mozilla Firefox.


Safari has no plug-in management at present.

Is the error message “Browser and system configuration not supported” displayed?

This error occurs when you attempt to install Microsoft Silverlight on an incompatible computer.
